  • Mold casting process and apparatus and method for producing mechanical parts
    Patent number: 5263532
    Abstract: A mold casting process comprises, after pouring of a molten metal into a mold, rapidly cooling that surface layer of a cast product which is in contact with a mold, and releasing the resulting product from the mold when the surface layer thereof has been converted into a shell-like solidified layer. Such process is used for casting a mechanical part blank and apparatus for carrying out the process is provided.
    Type: Grant

  • Casting process
    Patent number: 4727923
    Abstract: A casting process which is disclosed herein comprises placing a breakable core into a cavity in a mold and pouring a molten metal under a pressure into the cavity by means of a plunger. The casting process is characterized in that the speed of plunger moved is controlled at three stages of first, second and third velocities, the second velocity being set higher than the first velocity and the third velocity being lower than the second velocity.
